Dongfeng Road Sweeper Overview Dongfeng Road Sweeper is popular with users all over the world for its superior product quality and affordable price. Sweeper truck As one of the sanitation equipments, the road sweeper is a new type of high-efficiency sweeping equipment integrating road sweeping, garbage recycling and transportation. It can be widely used in road highways, municipal and airport pavements, urban residential areas, and parks. Pavement sweepers not only clean trash, but also dust and purify the air medium on the road, which not only ensures the beauty of the road, maintains the sanitation of the environment, but also maintains the good working conditions of the road surface, and reduces and prevents traffic accidents. The occurrence and further extend the life of the road. At present, the use of pavement sweepers for road maintenance in China has become a trend. The road sweeper is a special sanitation vehicle equipped with a sweeping brush and other cleaning systems. It is mainly used for sweeping operations in large and medium-sized urban sanitation departments. Road sweepers have greatly liberated the work intensity of sanitation workers, increased work efficiency, and reduced secondary pollution such as dust.

The device can ensure the automatic disengagement of the secondary engine from the fan when the secondary engine is started with no load and the secondary engine is stopped, simplifies the operation, reduces the impact of the secondary engine, and improves the reliability and service life of the secondary engine. At the same time, in addition to the display of the working speed of the secondary engine, there is an automatic record display of the cumulative operating time, which is easy to use, maintain and manage. The cleaning device has the automatic evasion protection function and the automatic reset function (has obtained national patent). After the sweeper encounters an obstacle, it automatically retracts and automatically resets after crossing the obstacle. This function effectively solves the problem that the cleaning device is easy to damage. The speed of the squeegee can be adjusted according to a variety of different sweeper decorations to select the high, medium and low gears, so as to ensure a good sweeping effect under various pollution conditions and reduce the operating cost accordingly. The injection-molded slice brush is quick and easy to replace, and there are steel plate brushes available. The structural arrangement of the “four-disc brush in the center — rear suction nozzle” has a large cleaning width and high cleaning efficiency, and is conducive to the adjustment and maintenance of the cleaning device and the suction nozzle. Due to the short front suspension of the structure and the high ground clearance of the suction nozzle, the transitability of the entire vehicle during transit transportation is good. Pneumatic conveying system adopts high-efficiency dedicated fans for digesting and absorbing foreign advanced sweeping vehicle technology and fully floating suction nozzles that can be automatically leveled along the road. It has strong cleaning ability and low operating oil consumption. It is common for road waste, silt, small stones and light floating. Things can suck clean. The left and right front sweeps can work independently or in conjunction to ensure that the right front sweep or left front sweep is used to selectively work independently in use, if the right front sweep does not work The work not only reduces the width of the occupied road, improves the safety of the working vehicles and the passing vehicles, but also reduces the abrasion of the brushes and helps to reduce the operating costs. The unique manual pump emergency system ensures that when the auxiliary engine is stopped, the working device can be retracted and the trash can lifted to facilitate inspection and maintenance. The hydraulic system adopts the superimposed electromagnetic hydraulic valve group, which integrates height, neatly arranged, reliable work and convenient maintenance. All stainless steel liner bins and water tanks have large volumes and can be cleaned continuously for a long time. Control switches are centrally installed in the cab, and all electronic control operations can be completed in the cab with air conditioning.

Dongfeng series road sweeper function introduction 1, dry sweeper car introduction The dry sweeper is a new type of road sweeper. It does not use a brush or water, and all airflow operations depend on the principle of aerodynamics. Experts have identified domestic leading technologies and have independent intellectual property rights. Luoyang Chifeng The Lu Jie brand series of road sweepers independently developed, developed and produced by the company use air flow without brushes or water spray. There is no dust, no secondary dust, and the extensive use of Lu Jie vacuum cleaners will greatly reduce the air volume. The content of inhaled particles completely solves the problem of serious dust pollution. It is a modern, environmental-friendly and energy-saving new type of environmental sanitation product. Its environmental protection technology index is higher than the national industry standard. 2, the characteristics of multi-function full suction sweeper The multi-function full-suction sweeper is a new product developed with patented technology. It has changed the traditional way of brush cleaning with the brush of the sweeper. It uses the air flow to complete the operation, and uses air flow to collect dust and garbage. It is very efficient because it is stored. This product can effectively reduce dust pollution, improve air quality, reduce the content of inhalable particles in the air, and improve people's living environment. Its characteristics: · Full suction dry sweeper. All the work is done with air flow, blowing and suction combined, no secondary dust. · Do not use water without brush, save energy, dry suction, the car is over, the ground is clean. · The cleaning effect is good. From tens of micrometers of dust to ordinary pebbles, leaves and other debris can be effectively removed, cleaning efficiency of more than 98%, can be described as "sweep ten times better than smoking again." · Simple structure, few wearing parts, easy to use and maintain, easy to operate. · Use and maintenance costs are low.

Vertical Disc Injection Molding Machine

The working principle of the disc Vertical Injection Molding Machine is to use the thrust of the screw (or plunger) to inject the plastic in the molten state (i.e. viscous flow state) after plasticization into the closed cavity, and then get the product after solidification.


Injection molding is a cycle process, each cycle mainly includes quantitative feeding, melt plasticity, pressure injection, mold filling cooling and mold opening. Take out the plastic part, and then close the mold for the next cycle.


Generally speaking, the molding process of the screw disk injection vertical Injection Molding Machine is as follows: first, add granular or powdered plastic into the cylinder, melt the plastic through the rotation of the screw and the heating of the outer wall of the cylinder, then close the mold, move the injection seat forward, make the nozzle close to the pouring port of the mold, and then inject pressure oil into the injection cylinder to push the screw forward, so that the high pressure can inject the melt into the closed mold with a relatively low temperature at a faster speed. After a certain period of time and pressure maintaining (also called pressure maintaining) cooling, solidify it into shape, and then open the mold to take out the product (the purpose of pressure maintaining is to prevent the melt from flowing in the mold cavity in reverse, supplement the mold cavity material, and ensure that the product has a certain density and dimensional tolerance). The basic requirements of injection molding are plasticization, injection molding and molding.
